Spring finger is a new type of electric connection in high voltage switch industry. It has the advantages of simple structure, convenient installation, strong flow ability and cost saving. It can greatly reduce the labor intensity and production cost by applying the closed assembly.

1, the structure is simple, the volume is small, the cost is low, the cost is low, the requirement of small size in the design of the device is satisfied, it is suitable for the compact design, and the minimum number of components simplifies the design of the connection device.

2, multi-point contact and high concentrated force can achieve almost lossless contact. Ensure larger current carrying capacity, good electrical conductivity, high electrical and thermal stability.

3, the contact pressure of each contact point is not high and has good wear resistance.

4, the unique structure makes it have a wide range of work; it allows large tolerances on the contact surface; it is more adaptable to machining errors and assembly errors, and is more suitable for large-scale production.
